Patent Nb. 364,880, dated June 14, 1887.

To all whom it may concern:

Beitknown that I, AURIN W001), of Worcester, county of Worcester, andState of Massachusetts, have invented an Improvement in Spindle-Supportsfor Spinning-Machines, of which the following description, in connectionwith the accompanying drawings, is a specification, like letters on thedrawings representing like parts.

This invention has for its object to simplify and cheapen the productionof that class of tntes the sole lateral bearing for the spindle, andwherein the bolster is held loosely, so as to compensate for or obviateinjurious jar or gyration in the spindle.

In accordance with myinvention the bolster, made as a rigid sleeve andconstituting the sole lateral support for the spindle above thebolster-rail and within the sleeve-whirl, is extended below the step toform a shank, the said shank entering loosely a socket made in thebolster-rail, the shank being so constructed or held as to permit thebolster to have a limited movement with the spindle as the lower end ofthe spindle moves under an unbalanced load. For the best results theshank of the bolster, made asalongitudinal prolongation thereof belowthe step, is made as a split sleeve to constitute springarms; yet thisshank may be solid and be loose in the socket, and be surrounded or not,as desired, by a fibrous or elastic packing of usual construction.

In this my invention I am enabled to do away with the usualbolster-case, thus dispensing with one piece, and by extending only thebolster, made as a single tube, into the sleevewhirl,,the latter may bemade of smaller diameter than when a bolster-case with a loose bolsteris employed within the whirl.

Figure 1 shows my improved bolster, the bolster-rail to hold it,packing, and sleevewhirl, all in section, the spindle shown in thebolster being in elevation; Fig. 2, a detail of the bolster alonewiththe packing removed; Fig. 3, a section of Fig. 2 in the dotted line a,and Fig. 4 a modification showing the shank made solid and surrounded byelastic packing; and Fig. 5,- a like section with the packing omitted.

The spindle .9, having a pintle, p, and the sleeve-whirl w are all asusual. The bolsterrail A, herein shown as T-shaped in cross-section, ismade thicker than usual, and its thickened portion is provided withsockets a-one socket for the shank of each spindle-bolster.

My improved bolster consists of a tubular portion, b, bored to receivethe pintle p of the spindle s, the latter running upon a suitable step,0, in the bolster, which is closed to constitute an oil-well. Theexternal diameter of the bolster is enough smaller than the internaldiameter of the sleeve-whirl to enable the latter to surround but nottouch the bolster,which only is interposed between the pintle andsleeve-whirl. The bolster has a shank, d, forming a continuation of itin the line oi the pintle-receiving socket or portion I), the said shankextended below the step being preferably composed of a tube-like portionslot-ted at two or more places to leave spring-arms d d, &c. Theexternal diameter of the shank d is such as to enable it to be inserteddirectly in the socket to in the rail A,where it will be held withoutthe intervention of a bolster-case in such manner that the said bolsterWill be free to move therein in substantially any and every directionasthe foot of the spindle moves laterally when traveling with anunevenly-balanced load.

As herein shown, the bolster is provided with two series of projections,cf, which bear snugly against the rail at the interior of the socket a.The shank d has cooperating with it a pin or projection, g, whichrestrains the rotation of the bolster with the spindle.

If desired, the parts of the bolster-rail to the right and to the leftof thelines y y and y y,

respectively, may be omitted.

In Fig. l I have shown the shank of the bolster as surrounded by anelastic packing, h; but this packing may be omitted, as in Figs. 2 and5, and the shank of the bolster unprotected by the packing may be setinto the socket a.

In Fig. 4 I have shown the shank of the 5 bolster as made solid and ofuniform diameter, the shank being surrounded by an elastic packing; butthe packing may be omitted, the bolster-shank in that case looselyfitting the interior of the socket.

The bolster herein shown and described is very eilicicnt in operation,is very durable and simple in construction, is very cheap to produce,and is light in weight.

I do not herein claim a bolster having a spring-shank at right angles tothe pintle-receiving socket; nor do I claim a spring post or stud tohold the bolster upon or above the rail and at one side the longitudinalcenter of i the spindle.

I claim- 1. A spindlebolstcr consisting, essentially, of a socketedpintle receiving portion having a shank forming a prolongation of thesaid socketed portion, combined with a bolster-rail having a socketclosed at its bottom for the reception of the said shank, substantiallyas described.

2. A spindlebolster consisting, essentially, of a socketed pintlereceiving portion having a spring-shank forming a prolongation of thesaid sockeied portion, combined with a boister-rail having a socketclosed at the bottom for the reception of the said spring-shank,substantially as described.

:5. A spindi'e-bolstcr consisting, essentially, of a socketedpintle-rcceiving portion having a shank forming a prolongation of thesaid socketed portion, combined with a bolsterrail having a socketclosed at its bottom for the reception of the said shank,and with means,substantially as described, to restrain the rotationof the bolster inthe said socket.

A spindle-bolster consisting, essentially,

I of a soeketed piutle-recciving portion having a shank forming aprolongation of the said socketed portion, and the elastic packing interposcd directly between the shank of the bolster and the interior ofthe socket in the rail, combined with a bolster-rail having a socketclosed at its bottom for the reception of the said shank, substantiallyas described.

In. testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

AURIN \VOOD.
